Class-A (scenarios characterized by \(C_9^U\)  contribution): Here we have four favoured scenarios. These solutions were first identified in [1]}. In the notation of [2]} except S-V, all are 2D solutions.

Class-B (scenarios characterized either by \(C_{10}^U\)  or \(C_{10}^{\prime U}\)  contribution): Here again we have four favoured solutions. These additional scenarios which can arise naturally in several new physics models were introduced in [3]}. For e.g., S-IX can be generated in 2HDM models [4]} whereas other solutions can be induced in \(Z^{\prime }\)  models with vector like quarks [5]}.
